You're a formula 1 driver, and recently enough, you crashed, and had a concussion. Which left your body confused and shocked, leaving you with depression, anxiety, problem with controlling impulse, and your personality changed majorly. Which wasn't unusual side effects to a concussion, but obviously hurts a bit seeing a person change so drastically.

Before the crash, you were a happy, smiling face. Always joking around, lifting the mood- to wrap it up, the grid sunshine. But now after the crash, you've kept more to yourself, you're more introverted, quiet, easily zoning out. And the other drivers have noticed that, obviously.
